What brand model is the first choice for 4k movie camera?

What price do you want? If there is a civilian price,

Black Magic Production Camera 4K Digital 4K- Original Record

4K digital recording, imitating 35mm film.

The 4k digital machine produced after Sony F55 Red.

RED ONE SCARLET-X has a wide range of low-priced cameras in China, with high cost performance and complete lens groups.

Bmpc can choose ef bayonet, and so can red, so their lens group is complete.

Similarly, bmpc and red can use Zeiss's head, which is very awesome. The most beautiful publicity pictures including bmcc and bmpc are Zeiss' CP-2 head.

The price is not high.

Sony is an old factory, and its strength is definitely not bad.

Kineraw seems to be a new factory, made in China, and all the friends around it are useless, but the industry has a high evaluation.

Of course, if your budget is very abundant, then you can also choose to rent something with higher price, such as arri. It is almost impossible for individuals to rent this extremely high-end machine, and no one will rent it without sufficient mortgage. If you need such a high-end machine, you can contact a larger entertainment company in China. They may have some rented resources, but we haven't heard of any domestic company, including Huayi, which bought several arri and rented it out.
